TPS54292PWPR - Texas Instruments

The TPS54292PWPR is a highly efficient, dual-output, synchronous step-down switcher integrated circuit (IC) designed and manufactured by Texas Instruments (TI). This versatile power management component is well-suited for a variety of applications, including consumer electronics, networking, telecommunications, and industrial systems.

Key Features:

• Wide Input Voltage Range: The TPS54292PWPR operates with an input voltage range from 4.5V to 18V, making it adaptable to a broad spectrum of power supplies and battery technologies.
• Dual Output Channels: It includes two independent channels that can deliver up to 2A of continuous current each, which can be beneficial for systems requiring multiple regulated voltages.
• Synchronous Buck Converter: The synchronous design enhances efficiency by minimizing the voltage drop across the internal switches, particularly beneficial at lower output voltages.
• Adjustable Switching Frequency: The switching frequency is adjustable from 200kHz to 1.2MHz, allowing designers to optimize the trade-off between efficiency and external component size.
• Integrated MOSFETs: Built-in low RDS(on) MOSFETs reduce the external part count and save board space while providing high efficiency.
• Frequency Synchronization: It supports synchronization to an external clock, which is useful for noise-sensitive applications requiring a specific switching frequency or for reducing electromagnetic interference (EMI).
• Thermal and Overcurrent Protection: The device includes thermal shutdown and overcurrent protection to safeguard against operation outside of normal conditions.
• Power Good (PG) Outputs: Each channel has a separate power good output for easy monitoring of the system status and sequencing.

Applications:

The TPS54292PWPR is ideal for powering FPGAs, DSPs, microprocessors, and other digital loads. With its dual-channel output, it can efficiently manage the core and I/O voltages required by these devices. Its compact PowerPAD™ package and high level of integration make it a space-saving solution for densely packed PCBs.
